The wire must be sufliciently resilient to be I placed around a shank 5.Its ends, or legs, 10 are then lowered towards the key 6 until one hasentered the opening 7; the other leg may then be easily brought intoposition to enter the said opening. When this has been accomplished thewire is pushed down until its loop 9 rests around the upper side of theshank 5. 5

By flexing the legs longitudinally, both in the same direction it isfound that whichever one is over the other they may be more easily madeto rest against one another where they cross. Further when the wire isso placed
